[Nook Color General] ylixir:
I don't know what all you did to the internal memory, but chances are this will work to get back to stock.

If that doesn't work then

Softkeys works, and I use it, but it's...not intuitive...this page made things clear for me. Reading through this should get your n key working and whatnot.

Disabling the service in the softkeys settings was good for me. That stupid little button was always in the wrong place no matter where I put it and wasn't useful anyhow. I also didn't install home switcher or whatever. If you get your n button set wrong, you can just clear the defaults from the app settings for whatever app is set to the n button.

Sounds like you got it rooted and everything, but here is a link for reference anyhow.

A note on those instructions: youtube did nothing but crash on me. The purpose of logging in with youtube is to get your device linked to your google account so you can get into the market. I didn't use youtube, i think i used gmail or the market itself or something. I don't remember. I just uninstalled youtube, you don't need it. Youtube video's still download and play in the default video player if you visit youtube.com from the web browser.

As far as your options for operating systems. I haven't used froyo, and haven't spent much time with honeycomb, so grain of salt and stuff. Plus it really depends on what you need/want.

Note: after booting a fresh burn for the first time, just walk away for five minutes. I'm not sure why (maybe something to do with the not quite jit doing it's thing?), but it will be more stable if you do.

Froyo gives flash and slightly better performance over stock. I think video is on par with stock, but it could be worse, i'm not sure. It's almost certainly not better. I can't speak for stability, as I haven't tried it. I think bluetooth is possible but not realistic? I know occip got the chip responding, but I haven't seen anything indicating it's useable. Links in previous posts so i won't make another.

Cyanogenmod gives all that froyo gives plus bluetooth support. Video framerate is poor (movies, not games and whatnot). Stability isn't as good as stock. Mostly it's fine but every once in a while things start force closing like mad and i have to reboot. Also battery life isn't good with cyanogenmod. Sleep has been disabled as there is a bug with it. It will still last over a day without a charge though. It's what i use day to day. Really amazing and fast moving. Seems like every day a new major bug is fixed or a whole new piece of hardware is working. Linkie:

Honeycomb is really cool and it's amazing what deeperblue did (without much source omgwat?) but it's still kinda just a toy until google releases all the source code. No flash, no hardware accelerated video, no bluetooth, no reason to use it, other than aesthetics. Annoying ui glitches in portrait mode. Neat and worth an sd burn to play with, but not for using day to day in my opinion.

Of course there is no need to choose one! There are a couple option for multibooting in the forums and I intend to get around to combining a few to triple boot. Right now this is what I use:

I'm set up to boot rooted stock off internal memory and cm7 off of uSD

P.S. If you just want it to work and be a full tablet it might be worth the extra $150 or so for an IPad. The nook has been fantastically useful for my needs and I don't think i've had this much fun with a piece of kit since my first apple II. On the other hand I've wasted a fair number of hours reading about and "bricking" the thing so...ymmv depending on what your needs/wants are.
